Answer: It rounds to <u>28 km</u>
Explanation:
The units or ones digit is "7". The next digit over (9) is five or larger. This means we bump the 27 up to 28. Everything after the 7 is ignored.
So we could have something like 27.999871212512 and we still follow the same idea of focusing on the 27, bumping it up to 28, and everything else gets ignored.
The reason for this is because 27.9 is much closer to 28 than it is to 27. Draw out a number line to help see this. Split the region from 27 to 28 into 10 equal pieces. The 9th little piece represents 27 & 9/10 aka 27.9
Refer to the number line diagram below.
1) 15/15 which is 1
2)100/30 which is 3 1/3
3)8.2
4) too long sorry
Answer:
<u>1035 feet</u>
Step-by-step explanation:
Taking the tan ratio of the angle of elevation :
- tan 49° = h/900
- 1.15 = h/900
- h = 1.15 × 900
- h = <u>1035 feet</u>
Answer:
h= −15 /2
Subtract 6h from both sides.
Subtract 7 from both sides.
Divide both sides by 2.
To solve this problem you must apply the proccedure shown below:
1. You have the following logarithm:
<span>log(2)n=4
2. Therefore, you con rewrite it as below:
loga(b)=logb/loa
</span>
3. Therefore, you have:
log(2)n=4⇒log(n)/log(2)=4
4. Then, you obtain:
log(n)=4log(2)
5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:
log(n)=4log(2)
